Chemical Structure
Description
2-Propenoic acid, 2-methyl-, 2-ethylhexyl ester, homopolymer 25719-51-1 CHEBI:53382 PHEMA poly(1-{[(2-ethylhexyl)oxy]carbonyl}-1-methylethylene) poly(2-ethylhexyl methacrylate) poly(2-ethylhexyl methacrylate) macromolecule poly(hexyl ethylmethacrylate) poly(hexylethylmethacrylate) polyhexyl ethyl methacrylate (C12H22O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
